2mm pitch GT2 Belt Clamps

youmagine

Here are four 2mm pitch GT2 belt clamp designs - two double ended and two single ended, with vertical and horizontal attachment holes sized to fit 6-32 screws. The design accommodates a 9.5 mm wide belt, but you can easily modify the RSdoc or STL files to adjust the height for a 6mm wide belt, etc. The horizontal-holed clamps like the one in the photo secure the smooth side of the belt 6.38 mm from the mounting surface. You can also easily edit that distance. The vertical-holed clamps hold the belt 2mm from the mounting surface (or flipped over, flush with the surface), and you can adjust that as well. As shown in the photo, the belt wraps around the round post in each clamp then folds back on itself, with the doubled thickness of the belt fitting snugly into the slots. This design ensures the belt won't slip no matter how much tension is applied. I'm not sure why, but the 3D preview of the STL files displays dimensions inaccurately. Rest assured that these parts are all 11.5 mm tall, and some lengths may also be off in the preview. Don't worry about it - the STL files are accurate. I printed these solid in 0.2mm layers without a brim or support. I recommend using ABS over PLA because the part may be exposed to heat during printing, and it will perform better if it doesn't soften.
